POTATO-BUG EXTERMINATO R.

SPECIFICATION forming part of Letters Patent N0.424,422, dated March 25,1890.

Application filed August 26, 1889. Serial No. 322,048. (No model.)

T at whom it may concern.-

Be itknown thatI, ALBERT J. KUEHN, a citizen of the United States, and aresident of Cincinnati, in Hamilton county, and State of Ohio, haveinvented certain new and useful Improvements in Potato-BugExterminators, of which the following is a specification.

The object of my invention is to provide a cheap, convenient, andeffective device to be used in connection with liquid paris-green toexterminate potato-bugs.

The advantages and features of my invention will become apparent fromthe following specification and claims.

[5 In the accompanying drawings, forming part of this specification,Figure 1 is a view of my device as it appears upon the back of theoperator and in use. Fig. 2 is a sectional View of the nozzle, hose, andregulating device used by me; and Fig. 3 is a view in elevation of amodification of the parts shown and used in Fig. 2.

A represents the can proper, in which the liquid paris-green is placedthrough the lid B. The can A is preferably formed of the shape shown andmade of galvanized iron. It may be constructed otherwise. Two straps Care securely connected in any suitable manner at D to can A. Thesestraps are free at their other ends, and are provided at these ends withrings E. These straps in use are preferably crossed over the breast, asshown, and the rings E slipped overhooks F on the side of the can, thusallowing the can to fit snugly to the back and bringing it well up inthe back, as shown. These straps may be otherwise connected. At thelower corner of the can at each side I provide a tube, as

G, over each of which slips the hose H. The

other end of each hose H is provided with a ferrule I. This ferrule isso shaped that when the opposite end of the hose H is passed through theopening in the nozzle and pulled through the ferrule will fit snugly, asshown 5 in Fig. 2, in the forward end of the nozzle J and make aWater-tight connection. The noz- Z16 J has a very slight internal taperand is largest at the front or delivery end, so that the ferrule willcause the end of the pipe H to be tightly compressed when said pipe ispulled rearwardly through the nozzle; These nozzles J are preferably ofa cylindrical shape and formed with a head at their forward end,

as shown, having a hooked portion K. In this hooked portion K, Ipreferably pivot, as shown in Fig. 2, a regulator L. This regu lator iscomposed of two arms a a, pivoted at a as shown. Each arm a a isprovided with a roller a By pressing on the arm a with the thumb, asshown in Fig. 1, the size of the spray can be regulated as the arm apresses hose H down so that the stream of parts-green water will besmaller or larger according to the amount of pressure exerted bypressing on the arm a of the regulator L, and the stream can be entirelyout off by the requisite pressure on the regulator. This is foundnecessary when filling the can, and when used when the potato-vines aresmall and the hills far apart. The only difference in the regulatingdevice shown in Fig. 3 is that it is pivoted below and forces the hoseupward instead of downward. The dotted lines in Figs. 2 and 3 show howthe regulator works and the positions it assumes when mg ulating thestreams. This regulator may be differently constructed and regulated.

A spray-cap M is placed over the mouth of each nozzle. It is preferablyscrew-threaded, as shown.

iVith my device the operator can pass between two rows of potato-vinesand spray the liquid parisgreen as he pleases. If desired, only onespray-nozzle need be used and the parts of the device may be slightlymodified.

\Vhat I claim as new and of my invention 1s- 1. The combination, withthe flexible dis charge-pipe, of a nozzle tapered internally at I itsfront end, a ferrule in the end of the said pipe for compressing it inthe tapering portion of the nozzle when said pipe is pulled rearwardlythrough the nozzle, and a perforated spray-cap secured over the frontend of the nozzle, substantially as and for the purpose set forth.

2. The combination, with the flexible discharge' pipe, of the nozzleprovided upon one side and at its rear end with a handle portion, thehooked portion K opposite said han- 10o dle portion and at about themiddle of the nozzle and an internal tapering portion at its front end,a ferrule in the end of the pipe for securing it tightly in saidtapering portion, a perforated spray-cap secured over the front end ofthe nozzle, and the arms a a, pivoted to the middle portion of thenozzle and adapted to compress the flexible pipe behind thesaid ferruleand in front of the said handle portion on the nozzle, substantially as10 and for the purpose set forth.
